OUTLINE: Autologous peptide-specific activated lymphocytes (PAL), previously harvested from the patient following vaccination on a different protocol, are expanded and reinfused intravenously; this is followed by a 4 hour observation period. Patients then receive interleukin-2 (IL-2) administered subcutaneously 5 days a week for 2 weeks; the first dose of IL-2 is administered at least 4 hours after PAL infusion. Patients are followed once a month for 2 months after treatment.
